Question

This position-time graph describes an object's motion. Use it to determine the

Answer 1

We're happy that you're asking for the "displacement", because displacement is simply the straight-line distance between the start-point and end-point, and we don't care about any of the motions or gyrations along the way.

From the graph:

-- The location of the object at time-zero, when time begins, is  10 meters.

-- The location of the object after 6.0 seconds is  4 meters.

-- The distance between the start-point and end-point is

(final location) - (initial location)

-- So Displacement = (4 meters) - (10 meters)

Displacement = -6 meters
